M1000 HET Semitrailer…Watch Out For Wrong Way Bolts

Operators, take a close look at the number four street-side bogie (axle) on your HET M1000 semitrailer. Specifically, check for a welded drain valve at the bottom of the tank near the connector rod and connector rod end.

Now check the locknuts, NSN 5310-00-877-5795, and bolts, NSN 5305-00-719-5240, used on the connector rod, NSN 3040-01-371-7854. If the locknuts face the bottom of the trailer, they can snag the drain valve during steering.

In that case, your mechanic will need to reverse the locknuts and bolts so the locknuts are facing the ground. Make sure he uses new locknuts if the change is necessary.

Not all trailers have the welded drain valve. If the valve isn’t there, the locknuts should face the trailer’s bottom.

Small Arms BII…Going to the Field? Be Prepared

When units go the field, they should follow the Boy Scout motto: Be Prepared!
Unfortunately, it’s more often a case of “Uh-oh, I forgot to bring that.” That’s especially true with small arms. Units go the range and take nothing but weapons and ammo. Result: Gunners fire and fire through the same barrel until it’s ruined. Weapons need lubing but no one remembered to bring any lube. Gas systems get plugged but no one brought a reamer. An M2 needs to be headspaced and timed but there are no gages. Firing problems develop but no one has the -10 TM to consult for troubleshooting.
If you’re going to the range, be prepared. At the very least, you need these items:
o Each weapon’s -10 TM
o Correct lubricants
o Spare barrel for each machine gun
o Gas system cleaning tool for each M240 and M249 machine gun
o Headspace and timing gages for each M2 machine gun
o Barrel mitten for each M2
o Cleaning rod for each weapon
o Extractor tool for each weapon
And if it’s been a while since your unit has fired, arrange refresher training before going to the range. Your 91F small arms repairman, master gunner, COMET, or TACOM LAR can help with that.
A little preparation can easily prevent big problems.


M109A6 Paladin, M777A2 Towed Howitzer… Primer Removal Made Easy

Crewmen, a stuck or ruptured primer can shut a fire mission down fast. But that can happen during top-level firing with the M109A6 Paladin and the M777A2 towed howitzer.
Two tools are being added to the basic issue items (BII) for the Paladin and the M777A2. The ruptured primer extraction tool (PET), NSN 1025-01-530-5873, and primer removal tool, NSN 4933-01-646-5946, will help get your howitzer back in the fight in a hurry.
The following procedures for removing stuck and ruptured primers will be added to the TMs:
Stuck Primer Removal (Most Common)
1. Insert the drift end of the primer removal tool into the muzzle side of the spindle primer hole.

2. Push the tool in until contact is made with the primer casing.
3. Push primer out manually using the palm of your hand or by tapping on the large end of the tool with a hammer. Remove the primer magazine (M777A2 only).
Ruptured Primer Removal
1. Insert the PET through the breech end of the primer vent hole. Turn the tool slowly until the tap screws are secured into the ruptured primer’s casing.

2. Tap the handle with a brass hammer until the casing is securely gripped.
3. Quickly move the tool’s slide hammer from side to side to remove the stuck primer casing.
After either procedure, be sure to clean and lube the breech and bore evacuator just like it says in the TM.


Publications…Army Adds EPUBs Option

MS-6736-A Army-epub
There’s an exciting new option for learning on the go. A growing list of Army Doctrine Publications (ADPs) and Army Doctrine Reference Publications (ADRPs) are making the leap from ordinary portable document formats (PDFs) to electronic publications (EPUBs).
Besides making pubs easier to read on tablets and smart phones, this means that readers can also use bookmarking, highlighting or note-taking features built into their mobile devices. View a list of available EPUBs at:
http://armypubs.army.mil/doctrine/Browse_Series_Collection_1.html

In addition to EPUBs, some doctrinal manuals will have enhanced electronic books (e2Book) supplements. E2books include audio, video, animation, simulation and other imbedded multimedia. You can get the first e2Book for the ADRP 1, The Army Profession (Jun 15), at:
http://cape.army.mil/adrp-1/
Or from the Central Army Registry (CAR):
